The power domains exposed by the AOSS QMP driver control the load state resources linked to modem, adsp, cdsp remoteprocs. These are used to notify the Always on Subsystem (AOSS) that a particular co-processor is up/down. AOSS uses this information to wait for the co-processors to suspend before starting its sleep sequence. These co-processors enter low-power modes independent to that of the application processor and the load state resources linked to them are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior lets stop using the power-domains exposed by the AOSS QMP node and replace them with generic qmp_send interface instead.
